Q

Why are smaller airways a concern for infants and children?

A
  • Concern because they can choke easier due to occlusion
  • Inc. chance of asthma
  • Increased risk of SIDS (sudden infant death syndrome)(First year of life)

Q

Are irregular respirations normal for infants? If it is, when it it considered not ok?

A
  • It is normal BUT…. if lasts longer than 15 sec or baby changes color it is an issue
  • If its less then or greater than the range it isn’t good (30-60 respirations per minute)
  • Not breathing is not ok

Q

Developmental considerations in pregnant females

A

Respirations are deeper, Tidal volume increases by 40%, Diaphragm elevates, Physiologic dyspnea so increased awareness to breathe because diaphragm, Muscles and cartilage relax, fetus increases oxygen demand

Q

Atelectatic crackles

A
  • fine crackles, do not last, disappear after a few breaths, heard in the base usually
  • Due to when alveoli are not fully aerated and are deflated

Q

Children have barrel chest (chest around 2 cm smaller than head) when they are little, when does the head to chest become a 1:2 ratio

A

Age 6

40
Q

When should you take respirations in an infant

A
  • Obtain the most accurate respiratory rate by counting when the infant is asleep because infants reach rapid rates with very little excitation when awake.
  • Respiratory pattern may be irregular when extremes in room temperature occur or with feeding or sleeping.

45
Q

Hypoventilation

A

slow shallow breathing

46
Q

Cheyne - Stokes respiration

A

an abnormal pattern of breathing characterized by progressively deeper, and sometimes faster, breathing followed by a gradual decrease that results in a temporary stop in breathing called an apnea (30 seconds to 2 minutes)

47
Q

Biots respiration

A

an abnormal pattern of breathing characterized by groups of quick, shallow inspirations followed by regular or irregular periods of apnea

48
Q

A

COPD, emphysema and chronic bronchitis

49
Q

Barrel chest is common in which patients

A

COPD
Cystic fibrosis
Elderly Patients

50
Q

Pectus excavatum

A

Funnel chest

Breastbone sticks into the chest

51
Q

Scoliosis

A

Lateral curvature of the spine, severe impairs breathing, slight scoliosis wont impair breathing

52
Q

Kyphosis

A

Hunchback

53
Q

Pectus carinatum

A

Pigeon chest, breastbone pushed out

54
Q

Atelectasis

A

Collapsed shrunken section of the alveoli or an entire lung as a result of airway obstruction, compression of the lung, lack of surfactant

55
Q

Lobar pneumonia

A

Infection in lung parenchyma leaves alveolar membrane edematous and porous, thus RBCs and WBCs pass from blood to alveoli
“Consolidation” (alveoli filled with fluid, bacteria, RBC, WBC) common used when talking about pneumonia
-crackles and wheezing

56
Q

Bronchitis

A

Acute infection of the trachea and larger bronchi characterized by chronic cough, usually viral. Epithelium of bronchi inflamed. Large airways narrowed from capillary dilation, increased mucus production, loss of cilia function, and swelling epithelium.

57
Q

Emphysema

A

Caused by destruction of pulmonary connective tissue; characterized by permanent enlargement of air sacs distal to terminal bronchioles and rupture of interalveolar walls. Increased airway resistance. Cigarette smoking is the main cause
(hyperresonant)

58
Q

Asthma (reactive airway disease)

A

An allergic hypersensitivity to certain inhaled allergens, irritants, microbes, stress or exercise that produces a complex response. Vasoconstriction and inflammation

59
Q

Pleural effusion

A

collection of excess fluid in the intrapleural space with compression of overlying lung tissue
-tactile fremitus is decreased or absent

60
Q

Pneumothorax (3 causes)

A

Free air in pleural space causing partial or complete lung collapse. Usually unilateral. Can be 1) spontaneous with air entering pleural space through rupture in lung wall 2) traumatic air entering because injury to the lung wall 3) tension due to trapped air in pleural space increases, compressing the lung

61
Q

Hemothorax

A

is a collection of blood in the space between the chest wall and the lung (the pleural cavity). Decreases space in the pleural cavity

62
Q

Heart failure

A

Pump failure with increasing pressure on cardiac overload causing pulmonary congestion or an increased amount of blood present in pulmonary capillaries and air sacs deflate. Pulmonary capillaries engorged. Bronchial mucosa swollen

63
Q

Pulmonary edema

A

buildup of fluid in the air sacs, pinkish, frothy sputum, usually due to congestive heart failure. You will hear crackles

64
Q

Tuberculosis

A

inhalation of tubercle bacilli into the alveolar wall starts 1) initial complex is acute inflammatory response - macrophage engulf bacilli but do not kill them and tubercle turns to bacilli 2) scar tissue forms, lesions calcify 3) reactivation of previously healed lesions, dormant bacilli multiply producing necrosis, cavitation and caseous lung tissue 4) extensive destruction as erosion erodes into bronchus, forming air filled cavity

65
Q

Pulmonary embolism

A

Undissolved materials like a thrombus or fat globule that dislodges in the leg or pelvis and travel through venous system into the right heart and lodges causing pulmonary occlusion resulting in ischemia

66
Q

Lung cancer

A

Most fatal of malignancies, major cause is tobacco use and smoking. Four types: squamous ( central bronchi) Adenocarcinoma (periphery and escapes early detection) Large cell (periphery and tumors clustered) Small cell ( oat cell, compresses and narrows central bronchi)

67
Q

Why do you check hemoglobin levels when doing a CBC?

A

Assess for anemia to see how well the oxygen is perfusing through the body

68
Q

Why do you check WBC levels?

A

To see if there is an infection

69
Q

What should SP02 be between?

A

95 - 100

70
Q

When would you do a sputum evaluation

A

If patient has TB

71
Q

How would you check for impaired gas exchange?

A

ABG
O2 stats
Hyper-hypo ventilation
